i like a wet ant(sz. 14-20) fished either by itself with no weight or as a dropper from a dry. I tie mine basically like a fur ant, only i substitute black thread coated with SH hard as nails(nail polish) for the humps of the ant. This is a common pattern, and is very effective. The hard as nails is key. it accentuates the black coloring of the ant body, gives it a glossy look like the natural, and makes it "plop" into the water which often seems to be the trigger for a strike. The only thing i dont like about this pattern is that the rear "hump" often closes the hook gape some, making missed takes a little more common.
